AuraAmp-Audio play

The automated tests are currently verifying the audio models, multi-queue state management, and application strings. AuraAmp is built from the ground up for high-fidelity audio reproduction, drawing direct inspiration from powerhouse Android players including Poweramp, USB Audio Player PRO (UAPP), Neutron, and Musicolet. Features & Architecture 1. High-Res Audio Engine & Hardware DAC Routing Broad Audio Format Decoding: Support for FLAC, DSD64/128 (Direct Stream Digital), 32-bit Float WAV, ALAC (Apple Lossless), MP3 (320kbps CBR), M4A / AAC, and OGG. Bit-Perfect Direct Hardware Mode: Direct audio HAL routing to bypass Android's fixed 48 kHz system resampler and OS mixer for bit-exact transmission directly to DACs and headphone amplifiers. Hardware Output Engine Selector: Seamlessly switch between Hi-Res AudioTrack (Direct HAL), OpenSL ES Native Studio, AAudio Ultra-Low Latency, and Bit-Perfect Direct USB DAC. Internal 64-bit Double Precision Float DSP: High-headroom internal processing pipeline preventing digital inter-sample clipping and quantization artifacts. 2. 10-Band Parametric Equalizer & Harmonic DSP Studio 10 Precision Equalizer Bands: 31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, and 16kHz with ±12.0 dB adjustment and detent center at 0 dB. Real-Time Frequency Response Curve: Interactive spline curve rendered on Canvas displaying acoustic filter shapes and preamp level. Master Preamp Gain: -12 dB to +12 dB master preamp slider to avoid clipping when boosting frequencies. Audiophile Target Presets: Audiophile Flat, Harman Target Curve, Vacuum Tube Warmth, Acoustic Vocal Stage, Club & Sub-Bass Impact, and Treble Air & Micro-Detail. Harmonic Tone Controls: Dedicated Sub-Bass Boost, Treble Clarity, Stereo Soundstage Widening, and Left/Right Channel Balance. 3. Studio Telemetry & Visualizers Dual Stereo Peak VU Meters: Dynamic Left and Right channels calibrated from -60 dB to 0 dB with green, amber, and red peak indicators. 32-Band Spectrum Analyzer: Frequency bar spectrum responding in real time to playback dynamics. Interactive Waveform Seekbar: Poweramp-style waveform track scrubber with real-time scrub cursor, elapsed timestamp, and remaining track duration. Audio Stream Inspector (UAPP/Neutron Style): Comprehensive telemetry modal detailing Container, Codec, Native Sample Rate, Bit Depth, Nyquist Bandwidth, Bitrate, Dynamic Range (DR Rating), and DAC route. 4. Musicolet-Inspired Multi-Queue & Library Management Multi-Queue System: Switch between Queue 1 (Hi-Res Masters), Queue 2 (Acoustic & Jazz), and Queue 3 (Late Night Ambient) with a single tap. Format Filter Chips: Filter the entire library by format (FLAC, DSD, WAV, ALAC, MP3, M4A, or ALL). Comprehensive Browsing: Tracks, Folders (hierarchical storage tree), Albums (grid view), Artists, and dedicated Hi-Res Masters tabs. Storage Access Framework (SAF) File Importer: Tap "OPEN" to load any FLAC, WAV, DSD, ALAC, or MP3 file directly from device storage or scan device MediaStore audio.Built-in Audiophile Reference Library: High-definition reference masters with real synthesized PCM playback so you can test EQ bands, bass boost, and VU meters immediately.
